This paper introduces a small game that the authors plan on creating and discusses the code and algorithms implemented inside. The game is created using Pygame. Pygame is a set of python modules designed for writing 2D-games. The reason we use it is that Pygame is free and simple to operate for a new game designer. The game involves moving a character through a maze while eating coins along the path. The character is controlled using keyboard. The maze is randomly generated using various maze algorithms. Although the game is simple, the logics and algorithms included are useful for more complex games. This essay will introduce the maze algorithms and navigation algorithms needed for the game, as well as the code implemented.

The complexity of generating intricate and random mazes is a captivating challenge that finds applications in various fields, including computer science, mathematics, gaming, and simulations. This study presents an innovative approach by integrating two prominent perfect maze generation algorithms, Aldous-border (AB) and Wilson. Both are celebrated for their strong randomness and efficiency, yet their combination offers a novel way to optimize maze generation. Our research commenced with a detailed analysis of the relationship between the coverage rate, uniquely characterized by the AB algorithm, and map size. We then formulated a mechanism that transitions seamlessly into the Wilson algorithm, aiming to minimize time consumption. Through a series of carefully designed experimental trials, we hope to use a model to find the most suitable algorithm for switching to minimize the time it takes to generate a maze. These were subsequently evaluated and compared to identify the most fitting solution. Under the framework of our synthesized algorithm, an average time saving of 34.124% was achieved, demonstrating a promising enhancement in efficiency. Although still in the exploratory phase, the outcomes of this research provide foundational insights into maze generation's underlying principles and techniques. The outcomes of this research offer insights into maze generation and its applications and may serve as a useful reference for future studies and potential technological advancements.

This research centers on predicting drug-drug interactions (DDIs) using a novel approach involving graph neural networks (GNNs) with integrated attention mechanisms. In this method, drugs and proteins are depicted as nodes within a heterogeneous graph. This graph is characterized by different types of edges symbolizing not only DDIs but also drug-protein interactions (DPIs) and protein-protein interactions (PPIs). To analyze the chemical structures of drugs, we employ a pretrained model named ChemBERTa, which utilizes simplified molecular input line entry system (SMILES) strings. The similarity between drug structures based on their SMILES strings is determined using the RDkit tool. Our model is designed to establish and link heterogeneous graph neural networks, taking into account the DPIs and PPIs as key input data. For the final prediction of interaction types between various drugs, we use the Multi-Layer Perception (MLP) technique. This model's primary objective is to enhance the accuracy of DDI predictions by factoring in additional data on both drug-protein and protein-protein interactions. The forecasted DDIs are presented with associated probabilities, offering valuable insights to healthcare professionals. These insights are crucial for assessing the potential risks and advantages of combining different drugs, particularly for patients with diseases at different stages of progression.
